The generalized second law in phantom dominated universes in the presence of black holes

TL;DR

This paper investigates the validity of the generalized second law of thermodynamics in universes dominated by phantom energy with black holes, finding that the law is violated in both studied scenarios.

Contribution

It examines the generalized second law in phantom energy universes with black holes, revealing violations in specific cosmological models.

Findings

The law is violated in phantom dominated expansion scenarios.

Black holes do not uphold the generalized second law in these models.

Abstract

This Letter considers the generalized second law of gravitational thermodynamics in two scenarios featuring a phantom dominated expansion plus a black hole. The law is violated in both scenarios.
